Online detection method and device for peritoneal dialysis waste liquid

Abstract

The invention discloses a peritoneal dialysis waste liquid online detection method and a peritoneal dialysis waste liquid online detection device. Automatic detection, automatic recording, dynamic presentation and automatic sending of related notifications can be carried out on the whole process of drainage amount, drainage time and drainage speed information on line, and the color value and / or the turbidity value and / or the actual picture data of the peritoneal dialysis waste liquid are / is automatically and quantitatively detected in the detection process, therefore, observation fatigue of a patient is relieved, tracing and checking are facilitated, and real peritoneal dialysis waste liquid detection data with reference standards and bases can be conveniently provided.

Description

technical field [0001] The invention relates to the field of peritoneal dialysis and provides an on-line detection method and device for peritoneal dialysis waste liquid. Background technique [0002] Peritoneal dialysis (PD) is referred to as peritoneal dialysis. Peritoneal dialysis is to use peritoneal dialysis fluid and the patient's own peritoneum to clean blood, remove toxins and excess fluid in the body; peritoneum is the membrane around the abdominal wall, covering the stomach, Spleen, liver and intestines; a pipeline leading to the abdomen outside the body is implanted in the peritoneal cavity of the human body, and fresh peritoneal fluid is injected into the peritoneal cavity through the pipeline, and the peritoneal fluid stays in the peritoneal cavity, and the patient's blood Waste and fluid from the peritoneum are filtered through the peritoneum into the peritoneal dialysis fluid; the peritoneal dialysis fluid containing waste is passed out of the body through the...

Problems solved by technology

[0007] The Chinese patent "Application No. CN201921277346.0, titled peritoneal dialysis equipment" proposes to use a color sensor to identify the color of the waste liquid in the waste liquid container, so as to replace the visual detection of the color of the waste liquid, which has positive significance, but The detection items are single and the functions are limited, so it is not suitable for online detection

[0008] The Chinese patent "Application No. CN200980125966.5, titled peritoneal dialysis equipment" provides a mechanism for determining the color and / or turbidity of the dialysate, but the operator needs to select the appropriate color and / or turbidity according to the chromatogram , still inseparable from visual observation and subjective judgment, and the operation is cumbersome, and it is also not suitable for online detection

[0009] The above three technical solutions are essentially completed manually after the drainage process is over, and various human operations are inseparable from the detection, which is inconvenient to implement; these raw data are greatly affected by the external environment when they are collected, such as environmental Brightness; and these raw data are also easily affected by individual subjective consciousness when they are collected, such as differences in individual vision; the most important thing is that the relevant original detection data is qualitatively random and not quantitative. , the rationality of the original detection data obtained lacks reference standards and basis; the existing technical solutions provide extensive and inappropriate implementation methods for the detection of peritoneal dialysis waste fluid, and the reasonable authenticity of the obtained raw data is not good. These non-quantitative The random and random original detection data cannot be applied to future big data statistical analysis, there is no common basis for comparison, and the use value is extremely low
